V, This invention appertains to road gates and has for one of itsprimary object-s means arranged ata point distant therefrom and onopposite sides thereof for opening and closing the gate whereby personsin vehicles can conveniently actuate the gate without alightanothersalient object of the invention is the provision of a novel operatingmeans for a road gate which is so constructed as to hold the'gate,normally either in a closed or an opened position against swingingmovementthereby eliminating the necessity of providing a latch orfastener for the gate.

A further object of the invention is the provision of a novel weightedbar movable toward and away from a stationary bar, the bars, having atoggle connection therebetween with a drag link connected to the gateand to the toggle at the point of connection of the toggle links withmeans for raising and lowering the swinging bar at apoint distant fromthe gate, whereby upon raising of the bar the gate will be moved eitherto a closed or open position as the case may be according to the initialposition of the gate.

A further object of the invention is the provision of novel means forarranging the toggle between the swinging beam or bar and the stationarybar relative to the drag link of the gate so that the gate will be heldeither in its open or closed position by said toggle againstaccidentalswinging movement, the swinging bar or beam acting as a weightto hold the toggle in either one of its two positions and to facilitatethe swinging of the toggle over its dead center during the opening orclosing of the gate.

A still further object of the invention to provide an improved gateoperating mechanism of the above character, which will be durable andefficient in use, one which will be simple and easy to manufacture, andone which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in thenovel construction and arrangement of parts, as will be hereinafter morespecifically described, claimed, and

Serial No. 344,748.

illustrated in the accompanying drawings, in which drawings Figure 1 isa perspective view of the gate and the operating mechanism therefor.

Figure 2 is a side elevation of the gate showing the same in its openposition, parts thereof being broken away and in section.

Figure 3 is a horizontal section taken on the line 33 of Figure 2looking in the direction of the arrows.

Figure 4 is a view similar to Figure 2 showing the gate being moved toits closed position.

Figure 5 is a horizontal section taken on the line 5-5 of Figure 4looking in the direction of the arrows, and

Figure 6 is a detail perspective view of the toggle and the drag linkfor the gate.

Referring to the drawings in detail, wherein similar referencecharacters t esignate corresponding parts throughout the several views,the letter A generally indicates a gate and B the novel operatingmechanism therefor.

The gate A can be of any preferred or Q011- ventional construction andis connected at its inner end by means of hinges 10 to a gate ost 11positioned at one side of a roadway 12. The free end of the gate A isadapted to close against a post 13 arranged on the opposite side of theroadway 12 from the post 11. It to be noted that the post 11 extends anappreciable distance above the gate and the post 13.

Spaced from the gate and on the same side of the roadway as the post 11is a post 1% which is provi=tled with a slotted guideway 15. The posts11 and H are of substznitially the same height 2 d each have their upperend bifurcated 1 to for a purpose, which will be later described.

'lfhe operating means 5 for the gate A comprises a novel swinging beam20 which is connected at its inner end to the post 11 by means of apivot pin 21 directly above the gate A. The outer end of the lever ispreferably thickened to form a weight and the extreme outer end thereofis provided with a reduced extension or guide shoe 22 which is slidablymounted within the uideway 15 of the post 14..

and 26 respectively, which are of substan tially the same length. Thelinks 25 and 26 of the toggle 24 can be formed in any desired way, out Iprefer to construct the-lower link 26 out of a suitable metal bar of thedesired gage and bend the same in substantially U- shaped form with thelegs thereof converging towardthe-ir outer ems. lhe outer ends of thelegs are provided with eyes 27' whioh register with the eye of an eyebolt 28car ried by the stationary bar. or beam adjacent to the post: 14;The upper link 25 is also preferably formed from metal bar of thedesiredgage of a substantially U-shape with the terminals of its legs formedwith eyes 29 receiving the bight portion of't'he link 26. The outer endof the link 25 receives the eye of an eye bolt 30 carried by theswinging beam or bar 20. r l

A drag link connection is provided between the toggle 24' and the gate Aand this drag link isindioated by there-ference character 32 and is alsopreferably formed from a metal bar of desired-gageofasubstantiallyV-sha-pe. The legs of the bar are provided witlieyesand arecoiled about the bight portion of the link 26 ofthe toggle 24. The bightportion of the drag link 82 is coiled to provide an eye 84 whichreceives a vertically disposed pivot bolt 35 carried by the gate. Theeye 34 is of great er diameter than the bolt so that the same can have aslight rocking movement thereon in a vertical plane as well as aswinging move' ment in a horizontal plane. If it is desired the eyebolts 28 and can also have a slight play in the bars'20 and 23.

In order to operate the gate from a point distant on opposite sidesthereof the bifur cated ends 1 6 of the posts 11 and 14 receiveoperating levers 36' and 37 and these levers are rockably mounted at apoint intermediate their ends on suitable pivot pins 38 carried by thesaid posts. T he inner ends of the levers are preferably heavier thanthe outer ends so that the same will norma ly swing toward the swingingbeam fZO by gravity. The same are connectedto the swinging-beam 20 bylinks 39 and 40, the links being pivotally connected to the inner endsof the operating levers 36 and 37 and to a common 41 carried by theswinging beam intermediate the ends thereof. I l j V s The outer ends ofthe operating levers are provided with pull handles 42.

In operation of the imoroved gate, when the gate isin its olosdposition. and when a pulliseXerted-"on either one of the hand pulls 42the swinging beam or bar 20 will be raised causing the toggle 24 tostraighten out and consequently exerting a pull on the drive link movingthe gate toward an open position. A sufiicient pull is given the handlesso as to swing the toggle 24 past its dead center and the weighted beam20 willthen swing down ward upon the release of the handle and thetoggle will swing on the opposite side of the posts 11. and 14 still.continuing a pull on the gate A moving the same to a complete openposition; I p 1 1 7 When it is desired to close the gate a quick pull isgiven either one of the handles 42 and the beam 20 will again be swungto a raised position on'its pivot straightening out the toggle 24consequentlypushingj on the 'lin'li 32 and moving the gate towardfitsclosed position. 1 Y As the toggle swings pastits dead center the weightof the-beam 20 will continu'e to push the gate to its closed position.

l Vhen the gate is in its closedposition as shown in Figure 1 of thedrawing it canbe seen that the same: is maintained in'thatpositionagainst accidental swinging movement due to the fact thattlie-piyot 34,27, and'29 willall be in the same horizontal plane which will preventt'lie'rbrealiing of the toggle. 1

W hen the gate is in itsv open position as shown in Figure 2 of thedrawing, the same will be maintained in that position against accidentalswinging movement due: to the fact that anypull on the, drag link'82will operate straight against the pivot-30and the bar 2001" beam willholdthe gate open.

From the foregoing description, it can be seen that l have provided anovel gate'mecha nism which will functiontoi quickly and easily open thegate at a point distant therefrom and which hold the gate either in anopen or closed position against accidental swinging movement. I I r Chnges indetails may. be made without departing from the spiritforthescope of this invention, but
